      <tt>
        <b>den=denom(r)</b>
      </tt> returns the denominator of a rational matrix.</p>
    <p>
    Since rationals are internally represented as
    <tt>
        <b>r=list(['r','num','den','dt'],num,den,[])</b>
      </tt>,
    <tt>
        <b>denom(r</b>
      </tt>) is the same as <tt>
        <b>r(3)</b>
      </tt>,
    <tt>
        <b>r('den')</b>
      </tt> or <tt>
        <b>r.den</b>
      </tt>
